I'd be willing to research(extra security options) and program the website.

I don't think centralization is the problem. the problem lies with a poor business model. It seems their business model is goaled directly at only security. Thats not a bad thing at all - in fact far from it.

But a business can not survive on just security alone.

It needs constant maintenance,Easily modifiable code for quick changes,Q/A team for website and public view of the services onions and frustrations.and most importantly and easy to use interface that is highly verbose.

I don't know that a new centralized solution is needed/wanted. If we want a centralized stock exchange, just improved/maintain GLBSE. I think a decentralized, peer-to-peer solution would be a step in the right direction though. Just my opinion though. I too am a software developer, and it would be quite interesting to be involved with either solution.

I would move halve my trading and cash there. The competition - in terms of price, reliability and redundancy of both exchanges - would be great for traders.

GLBSE were great in the beginning but I am becoming less and less convinced they should remain the sole exchange now.Competition is good for everyone, it gives buyers of services alternatives and drives sellers of services to do better.
